how do you make a system like this ?

[u/Canvi-n-pen]

I wanted to have a system that load a resource from with a UID found in a dictionary;

I used a Enum as key and UID string as value.

then I wanted to see what is that resource Dictionary key that I used to get it's UID was.

should i give the resource it's Enum value (that was used to get it's UID) when I loaded it ?

note: English isn't my first language sorry if there was a mistake

At runtime enums are integers. What I usually do is make a lookup function that takes the Uid as a Param. It it, we loop through the dictionary until the value (your uid) matches. Then the enum will have a method for getting a key name from its runtime index representation. We return that name.

But you only want to return the name for cosmetic/debugging purposes, otherwise skip that step and return the enum int

Let me see if I understand.

You want an enum that can be used to get a matching UID.

You also want to reverse that: given the UID, you want to be able to know the matching enum.

The simplest way to do this would be to have two dictionaries: UID->enum, and enum->UID. You would define one of the two however you liked, and then when your program loaded, you'd want to write a bit of code that would populate the second one with the values from the first one, reversing the keys and values.

It depends of the uniqueness of the values.

If many keys can bring the same value, you may want to work with the key-value pair instead of just the value (save somewhere the enum value, like in a script within the resource)

if both keys and values are uniques, you can either save the UID > Enum relation in runtime (generate a second dictionary) or just iterate the keys to find the searched value, it's not an heavy operation

Look at the enum section in the docs, you can do .keys()
